CLARENCE M. DAVIS, 0F CAPE MAY, NEW JERSEY.

VELOCIPEDE.

To all whom it may concern Be it known that I, CLARENCE M. DAVIS, a citizen of the United States, and a resident of Cape May, in thecounty of Cape May and State of New Jersey, have invented new and usefulImp'rovements in Velocipedes, of which the following is a spec1fication.

This invention relates to velocipedes.

An important object of the invention is to provide in a velocipede a means whereby the driving mechanism may be at will main tained in a state of rest with respect to the power delivering traction wheel.

A further object of the inventlon is to provide in at velocipede a means whereby an opposite rotative movement of the driving mechanism with respect to the rotation of the power delivering traction wheel may be utilized to produce a breaking effect upon the rear wheels.

A further object of the invention is to provide in a velocipede a, air of double acting oppositely influenced clutches, one of which is oppositely actuated upon the rotation of the driving mechanism in a'given direction, the other being actuated upon the rotation of the driving mechanism in an opposite direction.

A further object of the invention is to provide in a velocipede a means whereby the several clutches employed therein may be retained in a normal disengaged position with respect to the several co-acting elements in the absence of transmission of power to the driving mechanism.

A further object of the invention is to provide a velocipede of the above mentioned character which is strong, durable and'reliable in operation.

Other objects and advantages of the invention will be apparent during the course of the following description taken in connection with the accompanying drawings.

In the drawingsflforming a part'of this specification and in which like numerals are employed to designate like partsthroughout the same, j

In the drawings, wherein for the purpose of illustration is shown a preferred form of my invention, the numeral 10 indicates the main frame of a velocipecle constructed preferably of hollow tubing connected at its upper end to a head. 11. WVithin the head 11 there is arranged a vertical shaft 12 which terminates in a pair of forks 13 providing a shoulder 14; having engagement with the" head 11 as clearly shown in Fig. 9; The shaft 12 is provided with an adjustable shoulder 15 cooperating with the shoulder 14: to retain the shaft 12 within the head 11. The shaft 12 is provided centrally with a bore 16 having acommunleating slot 17. ,Within the bore 16 there is arranged a reciprocating rod 18 which is provided with a stud 19 projected through the slot 17. This'stud'is adapted for Q0 operation with an arm which encircles the shaft 12, the arm 20 being pivotally connected to ,alug21 ,7 carried within the head 11 by means o'fa'pin22'. To the arm-2U there is coiinected a'secoii'd arm 23whichin turn is connected to the twisted end '24 of a Bowden wire 25 having di-vergin'g ends 26, the twisted end 24 being arranged.With

in the frame 10 as clearly shown in Fig 9. In order to retain the arm 20 together With" the reciprocating rod 18 normally in the position shown in 9.the re ;is provided arranged within the head, the closure being secured in position bymeans of rivets 29 or the like having engagement with lugs 30 preferably formed, integral with the head 11." Within the lower ends of the fork member 13 there is journaled a spindle 31 having connected .at its ends'a pair of crank .arms 32. Upon the spindle31 there is rotatably mounted a hub 32 comprising 'a pair of receivers 33 and 34. In proximity to the receiver 33 there, is arrangeda disk 35 provided with a flange 36 having engagement with the inner periphery of the receiver 33 as elearlyshown in Fig. 2. The fiange36 by means of frictional engagement serves not only as a means for retaining the disk 35 in proper related position with respect to the receiver 33 but also as a means for retaining the ends of the spokes 37 of the power. delivering traction wheel 38. In

proximityto the receiver 34 there is arranged a ring 39 which is provided with a flange 40, the flange-4O functioning identical with the flange 36 of the disk 35. The

disk 35 is provided upon its outer face with an annular groove 41 adapted for thereception of lugs 42 carried at the ends of arcuate shaped clutch segments 43 which are arranged within a rotating housing 44.

Through thespindle 31 there is passed a v the arcuate shaped clutch segments 43 oppoa pin 45 having its ends projected through elongatedslots 46 provided by the housing 44. In order to normally retain the seg ments- 43 in their. respective positions as V vshown in Fig.-,3'there is provided a pair of elongated springs 47 and 48, the spring 47 .being connected tothe pin 45 as shown at 49, the other end of the spring being secured vto the housing 44 as shown at 50. The

spring 48 likewise has one of its ends connected to the pin 45 as shown at 51 "and its other end connected to the housing 44 as ,shown at 52. Upon the shaft '31 there is rotatably mounted a disk 53 which is provided'with an arm 54 and an annular, groove .55, the groove 55 being adapted for the re- L ceptionof lugs 56 'carried by the segments which are arranged within a housing 58. WVithin the spindle 31 there is arranged a pin 59 having its ends projected through openings 60 provided by-the housing 58. In order to retain the segments 57 normally in the position shownin Fig. 4 there is provided a pair ef spri rigs fil and 62, the spring 61 :being connected at one end to the pin 59 as shown at 63 while the other end is.

connected to the housing 58 as shown at The spring 62 is likewise connected atone end thereof to the, pin 59 as shown at 65 and has its other endconnected to the housing 58 as shown at 66. I e

The frame 10 is provided with a transversely disposed axle ;67 carrying V a pair of wheels, one of which is indicated as a whole by the numeral 68. Each ofgthe wheels 68 comprises a hub 69 provided with sockets 7 0 land 71.. In proximity to the socket 0 there is arranged a disk 72 provided with a flange 7 3. The flange 73 servesnot. only as a means for frictionally engaging the inner face of the. socket 7 0 thereby retainingthe disk 72 in position but also as a means for retaining the ends of the spokes 74 of the wheels 68. Within the socket 71 there is arrangednan annular ring-7 5- which serves as a means for retaining in position the ends of the spokes 74. The ring 75 carrie sa. flange 76. which is provided. with'an inner bevel face 77 adapted for engagementwith the cone-shaped end provided at its ends with apair of cam lugs 80 and 81 having engagement respectively with a lag v82 carried by the axle 67 and a portion of the frame 10 as shown, at 83, the

- 78 ofa brake plug 79. The brake plug 79 is a axle 67 and the lug 83 being carried. by the...

a frame 10; To the brake plug 79 there is connected an arm 84 which in' turn is connected to theend 26 of the Bowden wire 25. a

In use, whenthe spindle 31 is rotated in the direction of the arrow 7 the ends of the pin 45 moves within the slots 46 and consequently the pin is partially rotated with respect to the housing 44 whereupon pressure is exerted by thepin 45 upon-those ends of site the ends thereof which carry the lugs 42 whereupon the outer f ces of the lugs '42 frictionally engage the larger circumferential face within the groove 41 while the oppo- .site faces of theflugs 42 fric'tionally engage the smaller circumferential fac'e'within the groove 41, thereby locking the spindle 31 with respectfto' the hub32 whereupon forward rotary movement is transmitted tothe power delivering traction wheel. The relative position of 'one; of the arcuate shaped clutch segments 43,:and it lug-42' with re--fspect to 'the pin 45. when the spindle 3,1.is rotated in the direction of arrow f is clearly illustrated in Fig. 7. When the spindle 31 isrotated in the direction of the arrow 7 the pin 59 is brought to bear against these ends of the segments 57 at which the lugs 56 are carried and consequently the segments 57 are not moved from their normal position as shown in Fig. 4. Since the segments 57 are not moved from their normal position when the spindle 31 is rotated in the direction of arrow 7 no locking effect between the lugs 56 and the faces of the groove 55 is produced. When the spindle 31 is at rest with respect to the rotating hub 32? regardless of 31 is at rest no locking efi'ect is produced between the spindle ,31 and the hub 32 or between the spindle 31 and the disk 53. When it is desired to create a braking eflect upon the rear walls 68 regardless of whether the power delivering traction wheel 38 is moving forward or is at rest, the spindle 31 is I partially rotated in the direction of the arrow 5 shown in Fig. 2. As a result of the backward movement of the spindle 31 the pin 59 is brought to bear upon those ends of the arcuate shaped clutch segments 57 opposite the ends to which the lugs 56 are secured whereupon the segments 57 tend to rotate about the lugs 56 causing the outer faces of the lugs to engage the larger peripheral wall of the groove while the inner faces of the lugs engage the smaller peripheral wall V of the groove 55, thereby producing a locking effect between the spindle 31 and the disk 53. As a result of the locking efiect pro duced between the disk 53and the spindle 31 the arm 54 is moved with the partially rotating spindle 31 in which instance the reciprocating rod 18. is moved downwardly 7 against the influence of the spring 27. The

downward movement of the reciprocating rod 18 necessarily moves the arm 23. 7 Upon V the movement of the arm 23 a similar movement is transmitted to the arm 84 through the instrumentality .of. the Bowdenrwire 25. As a result of the movement of the arm 84 the cam 81 co-acting with the frame 10 at 83 forces the cone shaped member 78 into engagement with the face 77 of the flange 76, thereby imparting a braking action to the wheels 68. When the spindle 31 is partially rotated'in the direction of the arrow 7) the pin '45 exerts (pressure upon theends of the arcuate shape clutch segments 43 in proximity to the lugs 42 in which instance the segments 43 retain their respective'normal position as shown in Fig; 3 in which position the lugs '42 remain disengaged from the walls of the groove 41. WVhen the spindle 31 is moved forward in the direction of the arrow f the segments 57 through the instrumentality' of the spring 62 assume the position shown in Fig. 4 whereupont-he lugs 56 are disengaged from within the groove 55 and the arm 23 through the influence of the spring 27 is moved to the position shown in Fig. 9, thereby relieving the braking action upon the rear wheel 68.

It is to be understood that the form of my invention herewithshown and described is to be taken as a preferred-example of the same, and that various changes in the shape,

size and arrangement of parts may be resortedto without departing from the spirit of the invention or the scope of the subjoined claims. 7
